helicopter operations data for 2019
All helicopter flights in the London and London City Control Zones (CTRs) are subject to an Air Traffic Control (ATC) clearance due to the classification of airspace. Pilots navigate by visual reference to ground features with limited assistance from ATC and are responsible for ensuring that they fly in accordance with applicable Rules of the Air. Some of these rules are for the protection of third parties and the prevention of collisions, which include observing minimum weather conditions and selecting a safe height for flight that considers separation from obstacles (such as buildings and cranes) and the height of the ground.
For safety, operational and security reasons measures are in place that limit or constrain helicopter flights in some areas unless otherwise authorised. Some of these restrictions apply to all helicopters and some apply only to single-engine helicopters. Pre-determined routes have been established across the CTRs to assist with the integration of helicopter flights into the airspace, but it should be noted that pilots are often provided with an ATC clearance to transit through the airspace on more direct routings. In accepting an ATC clearance, the pilot still remains responsible for ensuring that they fly in accordance with applicable Rules of the Air.
The National Police Air Service (NPAS) and Helicopter Emergency Medical Services (HEMS) operate multi-engine helicopters, but their operations are subject to special requirements associated with the nature of the tasks they are performing. Therefore, NPAS and HEMS helicopters may need to operate at lower altitudes or hold over specific locations. In some cases, they may also be exempt from the regulations mentioned above.
